Question

  1. A. Magnetic fields: school bell electromagnet prediction shows Apply WS 2.2 when using diagrams to represent magnetic field patterns. because magnetic effects depend on field direction, current or changing magnetic flux.
  2. B. It swaps motor and generator reasoning. (measurement error).
  3. C. It describes gravitational force instead of magnetic force. (diagnosis error).
  4. D. It claims induced current is supplied by a cell. (prediction error).

Answer

Magnetic fields: school bell electromagnet prediction shows Apply WS 2.2 when using diagrams to represent magnetic field patterns. because magnetic effects depend on field direction, current or changing magnetic flux.

Explanation

Magnetic fields: school bell electromagnet prediction shows Apply WS 2.2 when using diagrams to represent magnetic field patterns. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Magnetic fields, uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The school bell electromagnet prediction detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.

Common mistake

generator-effect induction: avoid permanent and induced magnets

Treating permanent and induced magnets as interchangeable when answering about generator-effect induction.

Instead, identify the exact Unit 4.7 idea in Magnetic fields, then explain how it links to a current-carrying wire between magnetic poles and the objective to apply WS 2.2 when using diagrams to represent magnetic field patterns.
